Urban Dare Adventure Race is a fast-paced competition that challenges two-person teams to decipher clues, navigate the city, and perform playful stunts. A dozen trivia-based clues lead contestants to checkpoints all over Austin, where they must use a camera to document their presence and, in some cases, the completion of challenges. Unlike most Urban Dare races, participants will be on bike rather than foot or public transportation. Races generally last less than four hours, and the winning team receives free entry to the Super Dare, a cruise-based take on the Urban Dare concept that features a $5,000 grand prize. Proceeds from the race are used to help battle breast cancer.
With new races popping up weekly in cities around the world, the organizers of the Spartan Race are almost as busy as their race's runners. Almost. The grueling races range from the Spartan Sprint, which is a 5K with more than 15 obstacles, to the Ultra Beast, which is a marathon with more than 50 obstacles. Depending on the race, the obstacles may include mud pits, pugil sticks, or fire. To unite the sprawling operation, Spartan Race tracks racers' point totals on its online-standings page.
